I plan on using Ikan BP2T-SU battery plate that accepts Sony BP-U60 batteries which are rated for 14.4volts @ 3.9 amps, the same I use on my Sony F3; plenty to run the BMCC and quite compact for run and gun. This as back up power when the internal battery gets low.
When I move to studio mode, I will use V lock battery plates on my rails that I have configured with both 12 volt and 7.4 volt outputs. here is an example of the plate I will use for hand held. You can get them for under $30.
